Strokd dad's car has a stock block w/the edelbrock 6039's 2.02/1.6's and an E cam w/1.6's...I was going to attempt putting my 6039's on a stock 93 motor, but was too concerned with p/v issues so I didn't. The only way to know is check it for yourself. I know that doesn't help too much...You might want to try and stick to the smaller valved heads or notch your pistons

Since the stock pistons DO have valve reliefs, you MAY be able to get away with it, since you have a B-cam, which has a slightly bigger duration but lower lift than the E-cam. I wouldn't run anything bigger than a 1.6 rocker though. I am actually going through the same thing with mine, but I am going with 1.90 valves (not much bigger than stock), 1.6's, and an E-cam. As was mentioned above, STROKD's dad's car had the same 2.02 heads on a stock block, with 1.6's and an E-cam, and didn't have any problems. Research NEVER hurts though.
